Details:

When I set the font on a text object, it is rendered properly in the plot
window.  However, when I print to a Postscript format, the font is ignored and
replaced by Helvetica.  This is bad enough, but it affects many, many other
output formats which are generated first as a PostScript object and then
converted to their final form such as png or jpg.

Attached is a simple script to demonstrate the problem.


close all
graphics_toolkit qt
ht = text (0.5, 0.5, "Emerging, 1>2 RandD Services",
           "fontname", "arial","fontsize", 20);
print -color tstfont.eps
print -color tstfont.svg


If you look at the resulting eps file the text is tagged as belonging to the
Helvetica font.  The export to svg gets it right.

This may be a problem upstream with gl2ps.  I believe I am using self-compiled
version 1.4.0.
